PP0 Status• PP0 prototype v2 flex has been fabricated.• In use for prototype opto-board test.• Single PP0 flex will be laminated to PCB for initial system tests.

This will largely validate electrical design.• Many flexes will be laminated to composite panel as part of full

service panel prototype. Composite panel under fabrication, lamination in January.

• Full service panel prototype will include soldering of Type I cables to PP0 prototypes. This will be completed by summer 2003.

• By summer 2003 should also have results from system tests.• PP0 FDR in June 2003(along with service panels). PRR a few

months later.
